[Tlhaloso e akaretsang] Polyethylene ke polasetiki, e tsebahalang ka tekanyo ea eona e phahameng ea ho ba le boima bo feteletseng, ho tenyetseha le botsitso ba lik'hemik'hale. E loketse lits'ebetso tsa liphaephe tsa khatello le tse seng tsa khatello. Liphaephe tsa HDPE hangata li entsoe ka resin ea polyethylene 100, ka boima ba 930-970 kg/m3, e leng makhetlo a ka bang 7 ho feta tšepe.

Polyethylene ke polasetiki, e tsebahalang ka karolelano ea eona e phahameng ea bongata, ho tenyetseha le botsitso ba lik'hemik'hale. E loketse lits'ebetso tsa liphaephe tsa khatello le tse seng tsa khatello. Liphaephe tsa HDPE hangata li entsoe ka resin ea polyethylene 100, ka bongata ba 930-970 kg/m3, e leng makhetlo a ka bang 7 ho feta tšepe. Liphaephe tse bobebe li bonolo ho li tsamaisa le ho li kenya. Polyethylene ha e angoe ke ts'ebetso ea ho bola ha electrochemical, 'me ho tloaelehile hore liphaephe li pepesehe letsoai, asiti le alkali. Bokaholimo bo boreleli ba tube ea polyethylene bo ke ke ba bola, 'me khohlano e tlase, kahoo tube ea polasetiki ha e angoe habonolo ke kholo ea likokoana-hloko. Bokhoni ba ho hanela tšenyo ea ho bola le phallo e sa khaotseng bo etsa hore litlhoko tsa tlhokomelo ea liphaephe tsa HDPe li be tlase haholo. Pipe ea polyethylene e ka etsoa ka resin e matlafalitsoeng, e arotsoeng e le PE100-RC, 'me ea eketsoa ho liehisa kholo ea mapetso. Liphaephe tse hlahisoang li ka ba le bophelo bo bolelele ba ts'ebeletso, 'me polyethylene e na le monyetla oa moruo potolohong ea bophelo ea projeke.

Jwale kaha ho se ho entswe qeto ya ho tshwarella ha diphaephe tsa HDPe, moruo o bohlokwa haholo ha diphaephe tsa polyethylene di sebediswa ditshebedisong tsa meralo ya motheo ya paballo ya metsi. Ha ho bapiswa le diphaephe tsa tshepe tse ductile, molemo o totobetseng wa diphaephe tsa polyethylene ke hore di ka thibela ho dutla. Ho na le mefuta e mmedi ya ho dutla ha diphaephe: ho dutla ha manonyeletso, ho dutla ha ho phatloha le ho dutla ha mapetso, e leng ntho e bonolo ho e sebetsana.

Boholo baPhaephe ea HDPEe pakeng tsa 1600 mm le 3260 mm, 'me liphaephe tse kholo tse rekisoang hona joale li ka sebelisoa. Ntle le litsamaiso tsa phepelo ea metsi tsa masepala, liphaephe tsa polasetiki tse bophara bo boholo tse entsoeng ka polyethylene li ka boela tsa sebelisoa litsing tsa ho ntša letsoai metsing a leoatle le lits'ebeletsong tsa kalafo ea metsi a litšila. Liphaephe tse bophara bo boholo li ka ba ho tloha ho 315 cm ho isa ho 1200 cm. Bophara bo boholoPhaephe ea HDPee tšoarella haholo ebile ea tšepahala. Kamora ho patoa mobung, e ka sebetsa ka mashome a lilemo 'me ha e hloke tlhokomelo e ngata, kahoo e loketse haholo lits'ebetsong tsa kalafo ea metsi a litšila. Ho tšoarella ha phaephe ea polyethylene hoa eketseha ha boholo ba eona bo ntse bo eketseha, ho bontša ts'ebetso e makatsang ea ho thibela ho thothomela. Nka tšisinyeho ea lefatše ea Kobe ea 1995 Japane e le mohlala, meralo ea motheo ea litoropo; liphaephe tse ling kaofela lia hloleha bonyane hang ka lik'hilomithara tse 3, 'me sistimi eohle ea liphaephe tsa HDPE ha e na ho hloleha le ho hong.

Melemo ea phaephe ea HDPE: 1. Ho tsitsa ho hotle ha lik'hemik'hale: HDPE ha e na polarity, ho tsitsa ho hotle ha lik'hemik'hale, ha e ikatise bolele le libaktheria, ha e lekane, 'me ke sehlahisoa se sireletsang tikoloho. 2. Matla a matle a khokahano: sebelisa motsoako oa motlakase oa socket kapa motsoako oa butt, o nang le manonyeletso a fokolang le ho se lutle. 3. Ho hanyetsa phallo e tlase ea metsi: Bokaholimo ba ka hare baPhaephe ea HDPee boreleli, e na le coefficient e tlase ea ho hanyetsa ho tsofala le phallo e kholo. 4. Ho hanyetsa hantle mocheso o tlase le ho robeha ha bonolo: mocheso oa ho robeha ha bonolo ke (-40), 'me mehato e khethehileng ea tšireletso ha e hlokehe bakeng sa kaho ea mocheso o tlase. 5. Ho hanyetsa hantle ho robeha ha bonolo: Teko ea papiso ea ho hanyetsa ho robeha ha liphaephe tsa polyethylene le liphaephe tsa tšepe e bontša hore ho hanyetsa ho robeha ha liphaephe tsa polyethylene ho feta liphaephe tsa tšepe ka makhetlo a 4. 6. Ho thibela botsofali le bophelo bo bolelele ba tšebeletso: Phaephe ea HDPE e ka bolokoa kapa ea sebelisoa kantle ka lilemo tse 50 ntle le ho senyeha ke mahlaseli a ultraviolet.
